SonarRoom is a breakthrough iOS app that transforms any iPhone into a professional-grade room acoustics analyzer. Using augmented reality and real-time audio measurement, it builds a 3D acoustic map of any room in under four minutes — revealing standing waves, bass problems, echo issues, and the exact best listening position. What once required thousands of dollars of professional equipment is now in your pocket.

Why it matters

Room acoustics problems are the leading cause of poor-sounding audio at home, affecting everyone from music lovers to home theater enthusiasts to podcast creators. Until now, professional-grade acoustic analysis tools have been inaccessible to everyday listeners, but SonarRoom brings this technology to the masses.

The details

SonarRoom uses a combination of augmented reality spatial tracking and real-time acoustic signal processing to turn any iPhone into a 3D room acoustics analyzer. Users connect their iPhone to their speaker system, place the speakers in a 3D model, and walk around the room as the app plays test tones and measures the acoustic response. In under four minutes, SonarRoom builds a full 3D acoustic heatmap of the space, identifying issues like standing waves, bass null zones, flutter echo, speaker-boundary interference, and stereo asymmetry. The app also includes a "Sweet Spot Finder" that ranks the optimal listening positions based on multiple acoustic quality metrics.

• SonarRoom is available now on the Apple App Store for iPhone running iOS 17.0 or later.
